A PLACE TO RELIEVE THE STRESS CAUSED BY COVID 19
Each passing day brings news reports of the continued spread of the COVID- 19 virus and its horrible impact on people throughout our state, nation, and world. As a result, we all have to cope with increasing levels of anxiety, stress, and fear. Each of us has different ways in which we try to cope with these frightful times. One of the best ways I have found to deal with it is embark of a journey of discovery in my backyard. I would like to share with one such treks.
Recently after watching the noon news present the update on the numbers of cases of the pandemic in Georgia, I grabbed my camera and went outside to take a walk about. I was greeted with bright sunshine and balmy zephyrs. Standing on my deck, I was taken aback by a colorful collage created by the blossoms of jonquils, native and ornamental azaleas flowering dogwood, and other plants. After drinking in the beauty of this living mural, I began my walk.
One of the first things that caught my eye was a pipevine swallowtail nectaring at both yellow and orange blooms borne on native azaleas. I just had to stop and photograph this scene. A short time later, I just happened to notice a dragonfly flying just about my lawn. From time to time, the insect would land. Each time the dragonfly touched down, I was able to snap a few pictures as well as study the relative small aerial hunter. It was obvious that this was a species I had never seen in my yard before. The dragonfly was a female blue corporal.
Moving on I stopped in my tracks when a silver-spotted skipper landed in a patch of purple dead nettle. This marked the first time this spring I had seen this butterfly.
As I continued to walk, I noticed something different every few minutes. During one circuit, I spotted a eastern tiger swallowtail. During another circuit, I spied a cloudless sulphur. Carpenter bees seemed to be everywhere.
In subsequent trips around my yard, I stopped to study and photograph the fresh blossoms of flowering dogwood trees, bluets, and a native thistle.
Throughout my brief time afield, I was treated with the soothing songs of chipping sparrows and pine warblers singing from the tops our tall loblolly pines.
When I finally ended by backyard walk, sat in a chair on my deck, and began reviewing all that I had seen during my brief half hour backyard journey, Mother Nature surprised me with one final event. From around the corner of the house, a mockingbird appeared carrying a stick and quickly disappeared into the bowels of a nearby shrub.
I must admit, I wished that I could have extended my visit with my backyard neighbors; however, I had to address a few other demands on my time. However, when I went back inside, I was totally relaxed and convinced I need spend in my yard every day.
While aside of practicing social distancing, there is little that I can do to help thwart the spread of the terrible Covid-19 virus, I am certain that my backyard wildlife haven will help me deal with our uncertain future.
If you have your own wildlife haven, I hope you will visit it and your backyard neighbors often. I am certain each trip will help you unwind and strengthen your bond with the natural world during these turbulent times.
THE GREAT PURPLE HAIRSTREAK IS AN OFTEN OVERLOOKED BEAUTY
Each spring nature treats us to a kaleidoscope of beautiful plants and animals ranging from butterflies and moths to flowers and birds. In fact, with so many beautiful things to look at, nobody can appreciate them all. As a result, far too many stunning natural jewels go unseen. Take the case of the great purple hairstreak. It maintains its anonymity because its wingspan only measures 1-1.7 inches and it spends most of its life in the tops of trees. Consequently, although it is one of the most gorgeous butterflies we are likely to see in our backyards; it is safe to say most of us never spot one.
Recently my daughter stumbled across one basking on the lawn surrounding the place where she works. When she stopped to take a closer look at the butterfly, its beauty took her aback. The butterfly appeared to be what butterfly enthusiasts refer to as “fresh.” This means the butterfly recently emerged and was sporting undamaged wings cloaked with all of their scales.
If you see a male great purple hairstreak basking, it is something you will not soon forget. This is because the butterfly’s wings are a bright metallic blue and literally seem to shine in direct sunlight.
The upper side of the female great purple hairstreak is blackish in color and displays a limited amount of metallic blue.
Being an amateur photographer, one of the things on my bucket list is being able to photograph the dorsal side of a male great purple hairstreak. However, since the only time you are likely see the topside of this butterfly is when it is flying or basking, my chances of photographing it from above are limited. Consequently, all of my photos of it show the ventral side of the insect.
The undersides of the butterfly’s wings are best described as blackish in color and highlighted with red spots near when the wings join its body. In addition, a series of blue spots adorn the undersides of the hindwings.
Lastly, short, fragile tails extend from the trailing edges of the hindwings. If you look carefully at a great purple hairstreak you will likely see the butterfly moving these fragile tails back and forth. It is believed this is done to distract would-be predators. Supposedly, a bird or other predator is more apt to strike at the moving tails and not the insect’s head and body. This would give the butterfly a chance to escape before the predator realized its mistake.
One feature that immediately catches your eye when you spot one of these butterflies is its orange abdomen. Supposedly, this is a warning to predators that it is distasteful.
The best butterfly gardens offer butterflies host plants and to nectar-rich flowers. While we can offer great purple hairstreaks a supply of nectar, we cannot plant its host plant. The reason for this is its host is mistletoe. With that in mind, if you see mistletoe growing atop a tree such as oak growing in your yard, there is a good chance great purple hairstreaks are living in your neighborhood.
I should note that during the spring I most often see the great purple hairstreak nectaring on purple dead nettle (see accompanying photo). Purple dead nettle is an invasive introduced plant most homeowners would call a weed.
If you do not happen to spot a great purple hairstreak this spring, all is not lost. Great purple hairstreaks can be spotted throughout the state from March to early November.
BACKYARD SECRET — ONE OF OUR FOUNDING FATHERS CREATED THE COUNTRY’S FIRST DETAILED BIRD LIST
It goes without saying Thomas Jefferson is one of our most beloved Founding Fathers. While we are all aware of many of his multitude of interests, skills, and accomplishments, chances are you did not know he was fascinated with birds.
His deep interest in birds led him to pen a publication entitled Notes on Virginia in 1787. In this work, he listed less than 130 species of birds known to live in that section of the country. Historians tell us this represents the first detailed list of birds compiled in this country.
SAPSUCKERS HELP FEED HUMMERS IN EARLY SPRING
When the very first ruby-throated hummingbirds begin arriving in backyards across the state food is at a premium. This is because most of the flowers at that are blooming in early spring do not produce an abundance of nectar. As such, rubythroats must find other sources of food. In addition to our feeders, many hummingbirds rely on the sugary sap that collects in holes drilled in 246 species of native trees by the yellow-bellied sapsucker.
In case you are not familiar with this winter migrant, it is a woodpecker best known for drilling shallow holes in live trees. Often these holes are arranged in circles surrounding the trunk of a tree. Sap flowing through the tree collects in these cavities. In fact, in some cases, you can actually see where it oozed out of the cavities and dripped down the trunk of the tree.
The sap is a major source of food for the woodpecker. The sapsucker is able to dine on the sap because its tongue is equipped with an odd brush-like structure that it uses to collect the sticky liquid and bring it into its body.
Although sapsuckers often vainly try to discourage other wildlife from robbing their tiny sap-filled reservoirs, wildlife such as Carolina chickadees, squirrels, butterflies, moths, and ruby-throated hummingbirds often avail themselves of the food. Since the sap contains amino acids and sucrose, it is an ideal food for hungry hummingbirds.
It appears the food provided by the yellow-bellied sapsucker is more important to hummingbirds than we once thought. For example, rubythroats have been observed tailing sapsuckers through wooded areas seemingly to learn the location of active sapsucker wells. In addition, hummingbirds have been recorded actually trying to thwart other birds from feeding on trees containing sapsucker sucker holes.
It has also been demonstrated the northward migration of the yellow-bellied sapsucker closely mirrors that of the ruby-throated hummingbird. It should also be noted that when the rubythroats that nests in the northern limits of their breeding range, few nectar plants are blooming. This necessitates the birds to rely heavily on the sap collected in sapsucker wells to survive until nectar-bearing plants begin to bloom.
Chances are, if you have fruit or other hardwood trees growing in your backyard, they have been visited by the yellow-bellied sapsucker.
I guess you could say that when it comes to feeding hummingbirds early in the spring, yellow-bellied sapsuckers and we are the ruby-throated hummingbird’s best friends.
